Safety Precautions
1
Do not contact live pas of the module directly.
Do not disassemble modules or remove the nameplate or
any adhered pas.
Do not paint or paste any object on the suace of the
modules.
Do not focus sunlight on the modules using mirrors or
lenses.
No unattended children allowed near the modules.
Pulling on the junction box cable is strictly prohibited.
Do not place modules in areas where combustible gases
are likely to be generated or stored.
No stepping on module.

Safety Precautions
1
Do not place or throw weights on or onto the modules to
avoid damaging the glass.
No bumping of modules.
Metal jewelle is prohibited near the modules.
The use of non-insulated tools are prohibited.
No installations in rain.
The modules need to be reliably grounded. The PV array
grounding should be continuous and reliable, and the
grounding resistance should be less than 4Ω.

Current classication: The current is divided into 3 classes： H for the high class, M
for the middle class and L for the low class. The best practice is to only use modules
with the same power and current class within the same string during installation.
